Conversion formula

The conversion factor from feet per second to knots is 0.59248380129641, which means that 1 foot per second is equal to 0.59248380129641 knots:

1 ft/s = 0.59248380129641 kt

To convert 557 feet per second into knots we have to multiply 557 by the conversion factor in order to get the velocity amount from feet per second to knots. We can also form a simple proportion to calculate the result:

1 ft/s → 0.59248380129641 kt

557 ft/s → V_(kt)

Solve the above proportion to obtain the velocity V in knots:

V_(kt) = 557 ft/s × 0.59248380129641 kt

V_(kt) = 330.0134773221 kt

The final result is:

557 ft/s → 330.0134773221 kt

We conclude that 557 feet per second is equivalent to 330.0134773221 knots:

557 feet per second = 330.0134773221 knots

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 knot is equal to 0.0030301792766602 × 557 feet per second.

Another way is saying that 557 feet per second is equal to 1 ÷ 0.0030301792766602 knots.

Approximate result

For practical purposes we can round our final result to an approximate numerical value. We can say that five hundred fifty-seven feet per second is approximately three hundred thirty point zero one three knots:

557 ft/s ≅ 330.013 kt

An alternative is also that one knot is approximately zero point zero zero three times five hundred fifty-seven feet per second.
